en.Wedoany.com Reported - Recently, at the 25th Shanghai International Power Equipment and Generator Exhibition, Chongqing Cummins Engine Co., Ltd. in China unveiled a 19L multi-fuel platform methanol power generation engine, alongside the QSK38 new platform electronic control engine and the K50N gas engine. The 19L methanol engine achieves a thermal efficiency of 44.6%, reducing carbon dioxide emissions by approximately 18% compared to diesel engines, and can cut about 45 tons of carbon emissions per 1,000 hours of operation. It operates stably in environments ranging from -35°C to 50°C. The QSK38 new platform electronic control engine delivers a maximum power of 1,548 kW and maintains full power at altitudes up to 3,500 meters.
Chongqing Cummins Engine Co., Ltd., established in June 1995, is a joint venture between Cummins Inc. (NYSE: CMI) of the United States and Chongqing Machinery & Electric Co., Ltd. of China, with each holding a 50% stake. Headquartered in the Liangjiang New Area of Chongqing, the company specializes in producing heavy-duty diesel and gas engines with power outputs ranging from 200 to 3,500 kW, widely used in power generation, marine, construction machinery, and mining equipment. Founded in 1919 and headquartered in Columbus, Indiana, USA, Cummins Inc. is a global leader in power solutions. The joint venture operates two technology centers in China, with a research and development team of over 300 people and five test benches with a maximum power of 3,000 kW, achieving an annual production capacity of 23,000 units.
The 19L methanol engine features intake port multi-point injection, a high-energy ignition system, a Miller cycle-specific camshaft, and a high-efficiency turbocharger. Key components are designed with alcohol resistance and corrosion protection, overcoming technical challenges such as methanol fuel corrosion and cold-start difficulties. The QSK38 new platform electronic control engine incorporates a second-generation turbocharging system and Cummins' high-pressure common rail fuel system, with transient response performance meeting ISO 8528 standard G3 grade requirements, suitable for power generation, marine, and construction machinery applications. The K50N gas engine supports various gas sources, including natural gas, oilfield associated gas, and biogas, featuring intelligent fuel control and high-precision electronic fuel control technology. With high levels of component standardization and localization, its overhaul cycle can reach ten years, and it supports IoT platform-based condition monitoring and preventive maintenance.
Chongqing Cummins General Manager Chai Ruimin stated that the company invests no less than 5% of its annual revenue in research and development. As China accelerates the construction of computing power centers and digital infrastructure, data centers are seeing increased demand for highly reliable backup generator sets. Leveraging its supply chain control tower and end-to-end visual management system, Chongqing Cummins can achieve rapid global delivery within 18 days under predictive conditions. The company has equipped its new base in the Liangjiang New Area with rooftop photovoltaic and microgrid systems, and has deployed energy-saving equipment such as test bench power recovery. Previously, the company completed iterative upgrades to its K19, K38, and K50-G series diesel engines, improving product thermal efficiency to 41.6% and reducing carbon emissions by approximately 7%.
